The USB3320 is a highly integrated full featured Hi-Speed USB 2.0 transceiver based on Microchip's proven ULPI interface. The USB3320 provides an extremely flexible solution in a convenient 5 x 5 mm QFN package. It supports a wide variety of different reference clock frequencies with one single part, as well as accepting clocking from crystal/resonators and the ULPI 60Mhz Clock-In mode. As with previous generations of Microchip's USB transceivers, the USB3320 integrates a USB switch and both ESD and VBUS over-voltage protection devices.
